HENRY S. HALE, OF PHILADELPHIA, PENNSYLVANIA.

CHAIR.

SPECIFICATION forming part of Letters Patent No. 275,823, dated April1'7, 1883.

Application filed February 24, 1883. (No model.)

To all whom it may concern Be it known that I, HENRY S. HALE, a citizenof the United States, residing at Philadelphia, in the county ofPhiladelphia and State of Pennsylvania, have invented certain new anduseful Improvements in Chairs, of which the following is aspecification,reference being had therein to the accompanying drawlugs.

Figure l is a perspective view of a chair having my invention appliedthereto. Fig. 2 is a perspective View of my improved backframe.

The object of this invention is to facilitate the removal from a chairof that portion of the back which is ordinarily arranged between the twoupright posts wheneverit is found desirable to permit the backs to beconveniently repaired or beaten, or otherwise cleaned.

Referring to the drawings, AA are the front legs, B B the rear legs, and0 the seat, of the chair, which latter may be upholstered in anyapproved or desired manner.

D D are the posts, whichin practice I usually prefer to make each in oneand the same piece with the corresponding rear leg.

E E is a girt having its ends framed into the posts D D, its upper part,E, constituting a rib orweb for a purpose which will soon be explained.

F is a rod, tie-bar, or girt connecting the upper ends of the posts, andmay be either a round rod, as shown, or it may consist of a square orfiat bar of either wood or metal but in preference I prefer theconstruction shown.

K L M represent, respectively, the top, bottom, and one of the siderails of a back-frame, there being, of course, another side rail M atthe opposite ends of the top and bottom rails, thus constituting arectangular frame adapted to receive and support a suitable upholstering, which may be of any usual or approved construction. The top rail, K,is provided upon its rear side with a longitudinal upwardly-inclinedgroove or recess, 7t, adapted to receive the bar or girt F. The bottomrail is also recessed, as at l, to receive the upwardly-projeoiing ribE.

By an examination of the drawings it will be readily understood thatwhen either of the seat-backs is supported upon the girt E E and thegirt or tie-bar F, over which the recesses are adapted to fit, the backswillbe held firmly in position, and will not be liable to accidentaldisplacement, but can be readily removed from between the posts; and itwill also be seen that the rib E and tie-bar F are entirely concealed,and that as there are no joints or open crevices in sight the finishedappearance of the chair is not marred by any of the devices by means ofwhich the removal and displacement of the back are made possible.

It will of course be understood that so far as relates to supporting thelower end of the back the part E of the girt might be dispensed with,the ends of the rib E being attached to the posts by tenons and mortisesorotherwise.

Although in the drawings the ends of the girt E E and of the tie-rod Fproject through the posts D D, and are therefore visible, I prefer to soconstruct the parts that these ends do not'extend through to the outerfaces of the posts, or else cover them with some ornamental devices.

Although I have shown my invention as applied to an ordinary four-leggedand straightbacked chair of very plain design, I do not wish to belimited thereby, it being apparent that it is equally well adapted foruse upon other styles of chairs and the backs of various seats, such asare used in railroad-cars, streetcars, sofas, and similar articles offurniture.

One advantage of my invention is that it utilizes the transverse girtsor tie-bars, substantially such as are ordinarily employed, forconnecting the upper and lower ends of the back posts. Thus no increasednumber of parts is required beyond such as are frequently found inseat-backs.

It is evident that it would be difficult to form the groove lexcept withits walls parallel to the sides of therail L,and yet haveitlit closelythe rib E and be conveniently applied thereto, and it is also apparentthat it is desirable ,to form the girt E E in such manner that it shallserve as a part of the frame-work of the chair, whereas the groove ismay be formed with its walls at an inclination to the sides of the railK, and yet be conveniently applied to the girl:

-F; hence a construction which could be advantageously used in the toprail inight'be practicable for the lower rail.

What I claim is- 1.
